The first radiator 40 is provided on the first side surface 14 of the substrate 10 and is electrically connected to the feed-in unit 30 via a bullet, a microstrip, a coaxial cable, or the like. Thereby, the first radiator 40 obtains a current from the feed-in unit 30 and resonates a radio signal having the first center frequency. Further, the first radiator 40 has a “T” shape and includes a first series connection piece 42 (vertical portion) and a second connection piece 44 (horizontal portion). One end of the first contact piece 42 is electrically connected to the feed-in portion 30 and extends perpendicular to the first side surface 14. The other end of the first series connection piece 42 is connected vertically to the second connection piece 44. The extending direction of the second connecting piece 44 is the same as the extending direction of the first side surface 14 of the substrate 10.

本発明は、第一放射体４０のサイズを調節することによって、第一放射体４０が第一中心周波数が１７１０〜２１７０ＭＨｚの無線信号（例えば、ＧＳＭ１８００／１９００或いはＷＣＤＭＡ２１００）を送受信する際に、好ましい効果を得られる。   The present invention is preferable when the first radiator 40 transmits and receives a radio signal (for example, GSM1800 / 1900 or WCDMA2100) having a first center frequency of 1710 to 2170 MHz by adjusting the size of the first radiator 40. The effect can be obtained.

第二放射体５０は、金属材料からなり、ハウジング２２０に取り付けられる。例えば、金属フレームをハウジング２２０の外面に固定させるか又は射出成形法によって金属部材をハウジング２２０の内部に嵌め込ませて、金属フレーム或いは金属部材を第二放射体５０として使用する。本実施形態において、第二放射体５０は、互いに連接する第一延伸部５２及び第二延伸部５４を備える。第一延伸部５２は、長尺片状体であり、基板１０の第一側面１４に対して平行であり、且つ第一放射体４０の第一連接片４２と間隔をあけて設置される。第二延伸部５４は、長尺片状体であり、基板１０の第二側面１６に対して平行であり、且つ基板１０と間隔をあけて設置される。   The second radiator 50 is made of a metal material and is attached to the housing 220. For example, the metal frame is fixed to the outer surface of the housing 220 or a metal member is fitted into the housing 220 by an injection molding method, and the metal frame or the metal member is used as the second radiator 50. In the present embodiment, the second radiator 50 includes a first extending portion 52 and a second extending portion 54 that are connected to each other. The first extending portion 52 is a long piece-like body, is parallel to the first side surface 14 of the substrate 10, and is installed at a distance from the first series contact piece 42 of the first radiator 40. The second extending portion 54 is a long piece-like body, is parallel to the second side surface 16 of the substrate 10, and is spaced from the substrate 10.

本発明において、第一放射体４０及び第二放射体５０は、第二中心周波数の無線信号をカップリングする。また、第一放射体４０及び第二放射体５０のそれぞれの形状、及び第一放射体４０と第二放射体５０との間の間隔が調節されることによって、アンテナモジュール１００は、第二中心周波数が８２４〜９６０ＭＨｚの無線信号（例えば、ＧＳＭ８５０／９００或いはＷＣＤＭＡ Ｂａｎｄ５／８）を送受信する際に、好ましい効果が得られる。   In the present invention, the first radiator 40 and the second radiator 50 couple the radio signal having the second center frequency. In addition, the antenna module 100 is configured to have the second center by adjusting the shapes of the first radiator 40 and the second radiator 50 and the distance between the first radiator 40 and the second radiator 50. A favorable effect can be obtained when a radio signal having a frequency of 824 to 960 MHz (for example, GSM850 / 900 or WCDMA Band5 / 8) is transmitted and received.

連結部６０は、金属片体であり、半田付け等の方法を介して接地面２０と第二放射体５０との間に連接される。本実施形態において、連結部６０の一端は接地面２０における第二側面１６に隣接する側辺に連接され、連結部６０の他端は第二延伸部５４に連接される。連結部６０の、接地面２０と第二放射体５０との間における位置を変えることにより、第二周波数を有する無線信号の中心周波数を調節することができる。例えば、連結部６０の位置がフィードイン部３０に近づく場合、第二周波数の無線信号の中心周波数は高周波方向へ偏る。逆に、連結部６０の位置がフィードイン部３０から離れている場合、第二周波数の無線信号の中心周波数は低周波方向へ偏る。   The connecting portion 60 is a metal piece and is connected between the ground plane 20 and the second radiator 50 through a method such as soldering. In the present embodiment, one end of the connecting portion 60 is connected to the side of the grounding surface 20 adjacent to the second side surface 16, and the other end of the connecting portion 60 is connected to the second extending portion 54. The center frequency of the radio signal having the second frequency can be adjusted by changing the position of the connecting portion 60 between the ground plane 20 and the second radiator 50. For example, when the position of the connecting portion 60 approaches the feed-in portion 30, the center frequency of the second frequency radio signal is biased in the high frequency direction. On the other hand, when the position of the connecting portion 60 is away from the feed-in portion 30, the center frequency of the second frequency radio signal is biased toward the low frequency direction.

また、本発明の第一放射体４０は、「Ｌ」、「Ｆ」或いは「Ｓ」字状等に製造されても良い。   The first radiator 40 of the present invention may be manufactured in an “L”, “F”, or “S” shape.

また、第二放射体５０が閉鎖する構造ではないことを前提として、第二放射体５０を他の構造に設計しても良い。例えば、第二放射体５０は、第三延伸部（図示せず）をさらに備えることができる。この第三延伸部は、第二延伸部５４の第一延伸部５２から遠く離れた他端に連接され、且つ第一延伸部５２に対して平行である。   Moreover, you may design the 2nd radiator 50 to another structure on the assumption that the 2nd radiator 50 is not the structure closed. For example, the second radiator 50 can further include a third extending portion (not shown). The third extending portion is connected to the other end far from the first extending portion 52 of the second extending portion 54 and is parallel to the first extending portion 52.

また、上記の実施形態において、第一放射体４０と第二放射体５０との間の各所の間隔は互いに等しいが、他の実施形態において、第一放射体４０と第二放射体５０との間の各所の間隔は異なっても良い。   Moreover, in said embodiment, although the space | interval of the various places between the 1st radiator 40 and the 2nd radiator 50 is mutually equal, in other embodiment, the 1st radiator 40 and the 2nd radiator 50 are the same. The intervals between each may be different.

以下、本発明のアンテナモジュール１００の動作原理について詳細に説明する。先ず、第一放射体４０は、フィードイン部３０から電流を得た後に、第一中心周波数の無線信号を送受信する。次に、第二放射体５０は、第一放射体４０上の電流を感知すると、第一放射体４０とカップリングして、さらに第一放射体４０と共同で第二中心周波数の無線信号を送受信する。   Hereinafter, the operation principle of the antenna module 100 of the present invention will be described in detail. First, after obtaining a current from the feed-in unit 30, the first radiator 40 transmits and receives a radio signal having a first center frequency. Next, when the second radiator 50 senses a current on the first radiator 40, it couples with the first radiator 40, and further, in cooperation with the first radiator 40, generates a radio signal having the second center frequency. Send and receive.

図４から分かるように、アンテナモジュール１００は、中心周波数が１７１０〜２１７０ＭＨｚ及び８２４〜９６０ＭＨｚである時に、広い帯域幅を有する。   As can be seen from FIG. 4, the antenna module 100 has a wide bandwidth when the center frequencies are 1710 to 2170 MHz and 824 to 960 MHz.

上記の記載から分かるように、本発明のアンテナモジュール１００は、第一放射体４０を介して第一中心周波数を有する無線信号を送受信すると共に、第一放射体４０及び第二放射体５０を介して第二中心周波数を有する無線信号を送受信する。これにより、本発明のアンテナモジュール１００は、二重の周波数の信号を送受信できるため、帯域幅を広げることができる。また、本発明において、第二放射体５０が無線通信装置２００のハウジング２２０に設けられるので、アンテナのサイズを小さくすることができ、無線通信装置２００の小型化を促進することができる。   As can be seen from the above description, the antenna module 100 of the present invention transmits and receives a radio signal having the first center frequency via the first radiator 40 and also via the first radiator 40 and the second radiator 50. Wireless signals having the second center frequency are transmitted and received. As a result, the antenna module 100 of the present invention can transmit and receive a signal with a double frequency, so that the bandwidth can be expanded. In the present invention, since the second radiator 50 is provided in the housing 220 of the wireless communication device 200, the size of the antenna can be reduced, and the size reduction of the wireless communication device 200 can be promoted.

以上、本発明の好適な実施例について詳細に説明したが、本発明は前述の実施例に限定されるものではなく、本発明の範囲内で種々の変形又は修正が可能であり、該変形又は修正も、本発明の特許請求の範囲内に含まれるものであるのは、言うまでもない。   The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various variations or modifications can be made within the scope of the present invention. It goes without saying that modifications are also included in the scope of the claims of the present invention.
